I have updated the OID descriptions as noted below. Marc's corrections for AIGc and AIGn have been included however, for consistency with the UTG project, the descriptions for hcAIC was updated to the description that Health Canada provided. Also, while the NPN does include the DIN-HM codes, Health Canada refers to the entire set as the Health Canada Natural Product Number (NPN). Best regards, Joan Harper

*Note: Contains "boardcode", recommend viewing on forum. Plain text email will not show corrections properly. I have some concerns: 1. AIC: The updated description referring to foreign keys of various tables is inappropriate. The current description is better. 2. AIGc: The updated description should read: “Codes for a particular grouping of active ingredients. This is the 5 characters of the active ingredient code group number starting at position 3 and ending at position 7…” 3. AIGn: The updated description should read: “The AIG number is a 10 digit number that identifies products that have the same active ingredient(s) and ingredient strength(s). The AIGn is comprised of three portions:…” 4. NPN: The updated description refers to a DIN-HM. Are NPN and DIN-HM considered to be part of the same code system (2.16.840.1.113883.5.1107)? If yes, heading should be updated to NPN/DIN-HM (2.16.840.1.113883.5.1107). I also want to point out that several years ago (back in the SCWG days), the AIGc and AIGn were rejected as pan-Canadian standards mainly due to the fact that they are (were?) auto-generated numbers with no human review. This may have changed or may no longer be relevant, but I wanted to point it out. We want to ensure that these code systems are managed/governed as code systems should be as much as possible.

We met with Daniel Buijs from Health Canada yesterday to review all of the Health Canada Code Systems - (CCDD, DIN, NPN, AIGn, AIGc, AIC). In the course of that conversation, we received updated information for the Code Systems - mainly updated email addresses, updated descriptions, and links for more information. On Nov 13, we plan to update the metadata in the OID Registry for these code systems as follows: CCDD: (2.16.840.1.113883.2.20.6.1) Current: HPR-RPS@hc-sc.gc.ca Updated: clinicaldrug@infoway-inforoute.ca Current description: The Canadian Clinical Drug Data Set provides codes for identification and a consistent approach to naming of medications and medical devices in Canada.

The Canadian FHIR® Registry supports collaborative development in an effort to accelerate sustainable growth of FHIR, locally and internationally. The registry is the home of national FHIR profiles recommended for use in Canada, including extensions, value sets, URIs and other useful, commonly used components. It is also host to a growing number of national, jurisdictional and locally shared FHIR projects, and is open to all Canadian implementers.

The Canadian FHIR Registry offers:

  • seamless integration of profile editing using Forge (free FHIR profile editor)
  • designated project space
  • supports project teams of up to 100 individuals
  • online authoring of implementation guides
  • integration with source control tools such as GitHub
  • version controlled environment

The Canadian FHIR Registry blends software development best practices with the requirements of modelling in FHIR, essential to delivering successful project requirements while having continuous access to structure validation, rendering and publishing.

Service Level Agreement and Business Continuity

Simplifier.net should not be used in a production setting, as 24/7 support is not provided by Infoway or Firely®.

A project created in the Canadian FHIR Registry can be linked to an existing GitHub account. GitHub serves as a secondary backup and can sync the content in the project accordingly. Read details on how to set this up

Users of the Canadian FHIR Registry on the Simplifier platform can expect the following response time from the Firely team for any issue encountered.

Issue Premium Support Description

Forge License Agreement

As per the statement issued on the Firely blog,  Securing the future of Forge, the free version of Forge will be licensed for non-commercial use only starting January 1, 2020. To continue using Forge, users will need to be part of a paid plan on Simplifer.net. The current contract between Infoway and Firely for Simplifier.net allows for an unlimited number of users of Forge. Infoway has received confirmation from Firely that this will remain unaffected until December 31, 2021. If the authors in Simplifier.net belong to projects that are part of the Canadian FHIR Registry, they will be given rights through the administration processes of the platform conducted by Infoway.

The Canadian URI Project is a repository of identifier and code system namespaces. Capturing key metadata as FHIR® NamingSystem resources provides an automatic mapping of OIDs to URIs or vice versa.

To make the discovery of these artifacts more flexible, the Canadian URI Registry (alpha) was developed to allow artifacts to be queried via plain text, OID, URI or their respective identifiers. These identifiers are created according to the URI guidelines and posted to the FHIR Solution Architecture Workstream for approval.

It is important to note that all searchable artifacts are to be curated via the Canadian URI Project in Simplifier. There are ongoing discussions with the FHIR Solution Architecture Stream to have a single representative manage data for their respective jurisdictions.

A scheduled task is run periodically, making all new or modified artifacts searchable after a 20 minute window.

FHIR web services used to access terminology data

FHIR Terminology Service APIs enable automated exchange of clinical terminology content and resources. It allows developers to easily implement healthcare applications that programmatically consume codes and subsets without requiring in-depth expertize in the fine details of terminology.

terminology gateway APIFHIR Terminology Service API

 

A Uniform Resource Identifier (URI) is a globally unique string of characters that provides a simple and extensible means for identifying a resource. URIs are used to identify a namespace or the location of a resource. URIs are human-readable and offer the potential for resolvability. The HL7 FHIR® specification recommends using URIs to have all resources resolvable and to comply with the FHIR RESTful paradigm.

URI Registration Process

  1. Requestor shall first check that the URI does not already exist in the Canadian URI Project, Jurisdictional Registry (if exists) or HL7 FHIR Specification
  2. FHIR URIs must not be proposed for Subsets to be published on the Terminology Gateway as they will be generated automatically.
  3. Requestor shall contact the owner or respresentative for either:
  4. Forum posts shall have the following format:

    Subject: New URI Request
    • Description: “A description of the URI”
    • Responsible Body & Contact Information
    • Proposed FHIR URI: URI as per URI Guidelines
    • Existing OID (if exists)
    • To be published (optional): Jurisidictional repository/ Canadian URI Registry
  5. There will be a wait period of five business days for the communities to react to the forum post with comments, questions or requests for clarification.
  6. Update Forum post will be updated with the new URI.
  7. Publishing the URI in the Canadian URI Registry and Jurisdictional Registry. This is highly recommended to prevent any misuse or duplication of URIs but it is optional.

See a flowchart of the FHIR URI Registration Process (pdf).

Enhanced browsing of HL7 v3

Infoway HL7 Explorer is a powerful browser for HL7 v3 structures, vocabulary and references. Used in conjunction with the pan-Canadian releases, HL7 Explorer makes locating details and information more efficient.

In November 2017, the Canadian HL7 InfoCentral community determined that there was no longer any need to do further updates to the pan-Canadian Version 3 messages. As a result, the December 2012 releases of MR02.06.01 and CeRx 4.4.2 are the latest pan-Canadian publications of these standardized messages.

The HL7 Explorer, the Master Terminology Worksheet (MTW) and all other messaging related artifacts are aligned with the latest releases.

Pan-Canadian Standards use Object Identifiers (OIDs) to distinguish between objects by assigning a numeric string that enables other systems to understand the unique information that is being shared between various systems.

Canada Health Infoway (Infoway) has an arrangement in place with HL7 International that allows Infoway to submit OIDs to HL7 International on behalf of Canadian Implementers free of charge. There is a $250 USD fee per OID request if done directly with HL7 International.

To submit an OID, download the registration form that corresponds to your OID request.

  • For all non-jurisdictional and Infoway owned subsets, email the completed form to This email address is being protected from spambots. You need JavaScript enabled to view it.
  • All other requests must be sent to the Jurisdictional Representatives for OIDs
.

OID submission guidelines

  1. Jurisdictional Teams require 5-7 business days to process each request. It will be incumbent on the requestor to reply within this time frame to any questions and follow up as required. Any failure to do so will result in an automatic rejection and require resubmitting the request.
  2. The Requestor must post the OID requests on the following forums ONLY after consulting with the Jurisdiction/Infoway SME:
  3. Forum posts shall have the following format:

    Subject: New Namespace/CodeSystem/Subset OID Request
    • OID Description: “A description of the OID”
    • OID Symbolic name: Symbolic name guidelines
    • Responsible Body & Contact Information
    • Proposed FHIR URI: URI as per URI Guidelines
    • To be published: Canadian URI Registry/Terminology Gateway

  4. There will be a wait period of 5 business days for the communities to react to the forum post with comments, questions or requests for clarification.
  5. FHIR URIs must be proposed for all jurisdictional and non-jurisdictional OID requests according to the URI Guidelines and must be published in the Canadian URI Registry. Publishing the URI is an optional but highly recommended step. The Requestor will submit a validated FHIR® NamingSystem resource object based on the NamingSystem profile to their jurisdictional representative who will then upload it.
  6. FHIR URIs must not be proposed for Subsets to be published on the Terminology Gateway as they will be generated automatically.
  7. The Forum post will be updated with the new OID.

A webhook is an HTTP callback. When new content is published in the Terminology Gateway, a publishing event will be POSTed to each registered webhook, notifying their respective owners about the publication.

Webhook registration

Individual users can register for webhook notifications by sending an email to: This email address is being protected from spambots. You need JavaScript enabled to view it. and specifying the webhook endpoint. Upon registration, a unique api_id will be assigned to the webhook. Each notification POSTed by the Terminology Gateway will contain the api_id, allowing the endpoint to verify that the notification was indeed issued by the Terminology Gateway. The api_id must be echoed back by the webhook endpoint in the body of the notification response.

Webhook interface

The webhook endpoint must serve HTTP requests conforming to the following interface:

HTTP Request

{
  "api_id": "cb570e5a2748f349f9119431db836b3a23fdb6571afee34c0432d87220f2431b",
  "base_url": "https://termapi.infoway-inforoute.ca/rest/v1/",
  "notification_time": "2017110711:07:00",
  "targets": [
    {
      "id": "2.16.840.1.113883.2.20.6.1",
      "name": "Canadian Clinical Drug Data Set (CCDD)",
      "type": "package",
      "version": "20171016",
      "effective_date": "20171016",
      "publication_time": "2017103015:20:23",
      "message": "Monthly CCDD update for October 2017"
    },
    {
      "id": "2.16.840.1.113883.2.20.3.443",
      "name": "PrescribeIT",
      "type": "package",
      "version": "LPR2",
      "effective_date": "20171103",
      "publication_time": "2017110309:37:22",
      "message": "PrescriptionMedicinalCode version reflecting the October 2017 CCDD update"
    }
  ]
}
				
  • api_id: as previously mentioned, each notification POST contains the api_id granted at registration.
  • base_url: the base URL for the native REST API endpoint of the originating system. This can be used to call back the Terminology Gateway via APIs in order to programmatically download updated content.
  • notification_time: the timestamp of the webhook notification in yyyyMMddHH:mm:ss format.
  • targets: list of updated targets. Each entry in this array corresponds to a Terminology Gateway artifact (subset, codesystem, map, package) that was updated and is therefore subject to the notification. The target list will only include artifacts for which the user has registered to receive notifications. Users can register to receive notifications about content updates using the Terminology Gateway User Interface or by invoking the native REST APIs.

    Each of the notification targets contains the following fields:
    • id: the artifact id, typically an OID
    • name: the artifact name
    • type: the artifact type: subset, codesystem, package or map
    • version: the published version id
    • effective_date: the effective date associated to the artifact version, in yyyyMMdd format
    • publication_time: the publication time in yyyyMMddHH:mm:ss format
    • message: optional message describing the published artifact version

HTTP Request

HTTP Response code: 200 for success, any other response code will be interpreted as an error
Sample HTTP Response Body:

{
  "api_id": "cb570e5a2748f349f9119431db836b3a23fdb6571afee34c0432d87220f2431b",
  "result": "success",
  "message": "Successful processing of the webhook notification"
}
  • api_id: as previously mentioned, each notification response must echo back the api_id granted at registration.
  • result: success if the web hook notification was successful, any other value will be interpreted as an error.
  • message: optional response message.


Error handling

When receiving an error as a result of a webhook notification, the Terminology Gateway will retry the notification four times at 15 minutes intervals. If still unsuccessful after four notification attempts, the system will drop the notification and will notify the user by email that the webhook couldn't be invoked.
